To all whom among concern HENRY G. SHEER-R, oriwA KEGAN, ILLINoIs.

.HosE-oonrLInGi citizen of the United States, residing at? WTaukegan, in the county of f 'Lake and State of Illinois, have inventedfl certain new and useful Improvements in -l-lose Couplings, of

which the following is a specification.

idly to effect connection or disconnection between the two hose lengths; and insuring a perfect union of the hose lengths when will become apparent from the following description taken in connection with the accompanying drawings illustrating one practical embodiment of my invention:

In the drawings Figure l l is a longitudinaldiametrical sectionjof a coupling embodying my invention, cutting line 1-1 of Fig. 5; Fig. 2 is a longitudinal diametrical section, angularly separated from that of Fig. '1, and cutting line 2-2 of Fig. 5; Fig. 3 is a side elevation showi ing the two coupling members preliminarily jengaged but unlocked; Figal: is a detail 30 1. members ina locked position intermediate showing a central fragment of the two the initial or unlocked positionand the preferred final position; part of the structure {away to show a retaining being broken latch.

a In the embodiment of my inventionI preferably employ on both ends Jof each hose: section substantially duplicate coupling members. This is particularly advantageous 3 in fire hose, in that it 'makes no difference which end of any hose section is presented for engagement with another hose section,

the selection of male and female coupling a and obviously thedelays oftenincident to members appropriate PfOI connection are 1 avoided. In the drawings I have shown the two coupling members as exact duplicates and therefore I will describe but one of them, it

being understood that the opposing member is exactly similar in constructionwith like 1 parts indicatedxby like numerals of reference prime 3 distinguished by the exponent character In the drawings 10 indicates the hose section end secured within a sleeve 11 which I n a .Will term the compression sleeve.
